Not to be confused with Flying Attackers.

A Ghost Attacker is a type of attacker that appears in some TD games. It has the ability to ignore the presence of defences and move directly through them. They are often frustrating due to their ability to quickly traverse the entire map and cause quick loss of many lives, combined with their tendency to charge swiftly to the end; the towers most effective against them are usually those with either high enough damage to one-shot kill them or a high rate of fire. Sometimes, they are balanced with a specific tower type dedicated against them, such as in Bubble Tanks TD.
